As described above, according to the touch display unit of embodiment of the present disclosure can by by X touch electrode (X-TE), Y touch electrode (Y-TE), X touch electrode connecting line (X-CL) and Y touch electrode connecting line (Y-CL) arrangement are come within the same layer Promote the realization of the touch sensor arrangement in display panel (DISP).

In this case, touch electrode and touch electrode connecting line are touched according to X touch electrode connecting line (X-CL) or Y Electrode connecting line (Y-CL) is arranged to be arranged within the same layer around the mode of other touch electrode wires.In addition, each item touching Touching touch electrode connecting line included in electrode wires can have different length and arrangement, this, which will lead to, touches electricity by each item The imbalance for the capacitor that polar curve generates.

Figure 20 is the capacitor generated between touch electrode in the display panel illustrated according to embodiment of the present disclosure Exemplary view.

Figure 20 schematically illustrates the biography of the single-layer touch in the display panel (DISP) according to embodiment of the present disclosure Sensor structure, and show and generated between an X touch electrode wire (X-TEL) and adjacent Y touch electrode wire (Y-TEL) Capacitor example.

First X touch electrode wire (X-TEL-1) includes multiple X touch electrodes (X-TE) and a plurality of X touch electrode connecting line (X-CL).In addition, each X touch electrode (X-TE) can be connected by the X touch electrode being arranged between X touch electrode (X-TE) Wiring (X-CL) is electrically connected to each other.

First Y touch electrode wire (Y-TEL-1) to the 6th Y touch electrode wire (Y-TEL-6) includes multiple Y touch electrodes (Y-TE) and a plurality of Y touch electrode connecting line (Y-CL).In addition, multiple Y included in each Y touch electrode wire (Y-TEL) Touch electrode (Y-TE) can be by being arranged to the Y touch electrode connecting line (Y- around the first X touch electrode wire (X-TEL-1) CL it) is electrically connected to each other.

Since Y touch electrode connecting line (Y-CL) is arranged to around the first X touch electrode wire (X-TEL-1), Y touching Touch electrode connecting line (Y-CL) can be arranged to surround the first X touch electrode wire (X-TEL-1) all or part of.Separately Outside, since Y touch electrode connecting line (Y-CL) is arranged to surround X touch electrode wire (X-TEL), electricity can be touched in Y Capacitor is generated between pole connecting line (Y-CL) and X touch electrode wire (X-TEL).

In this case, Y touch electrode connecting line (Y-CL) included in Y touch electrode wire (Y-TEL) can root There is different length and arrangement according to the position of Y touch electrode wire (Y-TEL).Therefore, in each Y touch electrode wire (Y- TEL) difference may be present in the capacitor generated between X touch electrode wire (X-TEL).

For example, due to the first Y touch electrode connecting line (Y-CL- included in the first Y touch electrode wire (Y-TEL-1) 1) longest, therefore the part of the first X touch electrode wire (X-TEL-1) surrounded by the first Y touch electrode connecting line (Y-CL-1) Greater than the part of the first X touch electrode wire (X-TEL-1) surrounded by other Y touch electrode connecting lines (Y-CL).On the other hand, Since the 6th Y touch electrode connecting line (Y-CL-6) included in the 6th Y touch electrode wire (Y-TEL-6) is most short, the The part of one X touch electrode wire (X-TEL-1) surrounded by the 6th Y touch electrode connecting line (Y-CL-6) is touched less than the first X The part of electrode wires (X-TEL-1) surrounded by other Y touch electrode connecting lines (Y-CL).

Therefore, the electricity generated between the first Y touch electrode wire (Y-TEL-1) and the first X touch electrode wire (X-TEL-1) Appearance becomes maximum, and the electricity generated between the 6th Y touch electrode wire (Y-TEL-6) and the first X touch electrode wire (X-TEL-1) Appearance becomes minimum.

Above-mentioned capacitance difference between Y touch electrode wire (Y-TEL) will lead to the touch sensor of display panel (DISP) Capacity unmbalance in structure, to reduce touch performance.

It can by being applied in single-layer touch sensor structure according to the touch display unit of embodiment of the present disclosure Compensate touch electrode wire (TEL) between capacitance difference touch electrode (TE) structure, can prevent touch electrode wire (TEL) it Between capacity unmbalance and improve touch performance.

Figure 21 and Figure 22 is schematically to illustrate to be touched according to the single layer of the display panel (DISP) of embodiment of the present disclosure Touch the view of the structure of the touch electrode (TE) in sensor structure.Figure 21 shows the knot by means of Y touch electrode (Y-TE) Structure carrys out the example of compensating electric capacity difference.Figure 22, which is shown, carrys out compensating electric capacity difference by means of the structure of X touch electrode (X-TE) Example.

Referring to Figure 21, included X touch electrode (X-TE) is by being arranged in X in the first X touch electrode wire (X-TEL-1) X touch electrode connecting line (X-CL) between touch electrode (X-TE) is electrically connected to each other, and each Y touch electrode wire (Y- TEL included Y touch electrode (Y-TE), which passes through, in) is arranged to surround at least the one of the first X touch electrode wire (X-TEL-1) Partial Y touch electrode connecting line (Y-CL) is electrically connected to each other.

In addition, Y touch electrode (Y-TE) included in each Y touch electrode wire (Y-TEL) can have different faces Product.For example, Y touch electrode (Y-TE) Y11 included in the first Y touch electrode wire (Y-TEL-1) can have the smallest face Product, and Y touch electrode (Y-TE) Y16 included in the 6th Y touch electrode wire (Y-TEL-6) can have maximum area.

The area of Y touch electrode (Y-TE) can indicate the area of Y touch electrode (Y-TE) itself, or can indicate Y The area of touch electrode (Y-TE) generation capacitor.

For example, tune can be passed through in the case where Y touch electrode (Y-TE) is transparent electrode or opaque grid type electrode The size of open area in whole Y touch electrode (Y-TE) changes the area of Y touch electrode (Y-TE).Alternatively, Ke Yitong It crosses the ratio for the dummy pattern that change is arranged in Y touch electrode (Y-TE) and generates capacitor to change Y touch electrode (Y-TE) Area.

That is, the area of Y touch electrode (Y-TE) is construed as comprising Y in embodiment of the present disclosure Touch electrode (Y-TE) generates the area of capacitor, which adjusts according to the ratio of the size of open area or dummy pattern.

As described above, embodiment of the present disclosure can be by being for every by the rea adjusting of Y touch electrode (Y-TE) Y touch electrode wire (Y-TEL) and the difference different from each other to compensate the capacitor generated by each Y touch electrode wire (Y-TEL).

More specifically, the area of Y touch electrode (Y-TE) included in each Y touch electrode wire (Y-TEL) can be by It is configured to be inversely proportional with the length of Y touch electrode connecting line (Y-CL).

That is, the Y touch electrode connecting line (Y-CL) for being connected to Y touch electrode (Y-TE) is longer, Y touch electrode (Y-TE) area is smaller.

For example, as shown in figure 21, the first included Y touch electrode connecting line in the first Y touch electrode wire (Y-TEL-1) (Y-CL-1) it can be the 6th longest, and included in the 6th Y touch electrode wire (Y-TEL-6) Y touch electrode connecting line (Y-CL-6) it can be shortest.

In this case, Y touch electrode (Y-TE) Y11 included in the first Y touch electrode wire (Y-TEL-1) can be with With the smallest area, and Y touch electrode (Y-TE) Y16 included in the 6th Y touch electrode wire (Y-TEL-6) can have Maximum area.In addition, Y touch electrode (Y-TE) Y12, Y13, Y14 included in remaining Y touch electrode wire (Y-TEL) and The area of Y15 can be inversely proportional to the length for the corresponding Y touch electrode connecting line (Y-CL) for being connected to these touch electrodes.

The Y touch electrode (Y-TE) being connect by opposite reduction with longest first Y touch electrode connecting line (Y-CL-1) The area of Y11 can reduce the capacitor generated by the first Y touch electrode wire (Y-TEL-1).In addition, by that will be touched with than the first Y Touch Y touch electrode (Y-TE) Y12's of short the 2nd Y touch electrode connecting line (Y-CL-2) connection of electrode connecting line (Y-CL-1) Area increase to it is bigger than the area of Y touch electrode (Y-TE) Y11, can make by the 2nd Y touch electrode wire (Y-TEL-2) generate Capacitor is similar to the capacitor generated by the first Y touch electrode wire (Y-TEL-1).

It similarly, can be by being and each Y touch electrode wire (Y-TEL) by the rea adjusting of Y touch electrode (Y-TE) In the length of included Y touch electrode connecting line (Y-CL) be inversely proportional to reduce and be generated by each Y touch electrode wire (Y-TEL) Capacitor difference.

In addition, the Y touch electrode (Y-TE) being connect with the 6th Y touch electrode connecting line (Y-CL-6) with shortest length Y16 can be configured as with maximum area, so that by the capacitor of the 6th Y touch electrode wire (Y-TEL-6) generation and by the first Y The capacitor that touch electrode wire (Y-TEL-1) or other Y touch electrode wires (Y-TEL) generate is similar.

Y16 can be configured as included Y touch electrode (Y-TE) has in 6th Y touch electrode wire (Y-TEL-6) Maximum area, Y touch electrode (Y-TE) can not have open area (in the case where transparent electrode), or touch electricity in Y Dummy pattern can be not provided in pole (Y-TE) (in the case where opaque grid type electrode).That is, in order to compensate for electricity Tolerance is different, and included Y touch electrode (Y-TE) can be arranged to have different in each Y touch electrode wire (Y-TEL) Area, so that generating the Y touch electrode (Y-TE) of minimum capacity has maximum area, to prevent touch sensitivity from deteriorating.

Can by change X touch electrode (X-TE) area and by change Y touch electrode (Y-TE) area come Compensate the capacitance difference due to caused by the difference of Y touch electrode connecting line (Y-CL).

Referring to Figure 22, included X touch electrode (X-TE) is by being arranged in the first X touch electrode wire (X-TEL-1) X touch electrode connecting line (X-CL) between them is electrically connected to each other.In addition, included in each Y touch electrode wire (Y-TEL) Y touch electrode (Y-TE) pass through be arranged to surround the first X touch electrode wire (X-TEL-1) at least part of Y touch Electrode connecting line (Y-CL) is electrically connected to each other.

Therefore, because Y touch electrode connecting line (Y-CL) included in each Y touch electrode wire (Y-TEL) has not Same length and arrangement, therefore generated between each article of Y touch electrode wire (Y-TEL) and the first X touch electrode wire (X-TEL-1) Capacitor can be different from each other.

In order to compensate for the capacitance difference of above-mentioned Y touch electrode wire (Y-TEL), in the first X touch electrode wire (X-TEL-1) Included X touch electrode (X-TE) can have different areas.

For example, the first Y touch electrode wire (Y-TEL-1) with the generation maximum capacitor in Y touch electrode wire (Y-TEL) X touch electrode (X-TE) X11 being adjacently positioned can have the smallest area.In addition, in Y touch electrode wire (Y-TEL) X touch electrode (X-TE) X16 that 6th Y touch electrode wire (Y-TEL-6) of generation minimum capacity is adjacently positioned can have most Big area.

Similarly, as the capacitor by adjacent Y touch electrode wire (Y-TEL) generation increases, remaining X touch electrode (X-TE) area of X15, X14, X13 and X12 can gradually become smaller.

This may mean that the number with the Y touch electrode connecting line (Y-CL) being adjacently positioned with X touch electrode (X-TE) Amount is reduced, and the area of X touch electrode (X-TE) becomes smaller.

As described in the example in Figure 21, the area of X touch electrode (X-TE) can pass through X touch electrode (X-TE) The ratio of size, the size of open area formed therein or the dummy pattern being arranged therein adjusts.

As described above, when the capacitor generated by the Y touch electrode wire (Y-TEL) being disposed adjacent with X touch electrode (X-TE) When relatively large, electricity can be touched in Y touch electrode wire (Y-TEL) and X to reduce by reducing the area of X touch electrode (X-TE) The capacitor generated between pole (X-TE).Therefore, length and arrangement due to Y touch electrode connecting line (Y-CL) be can compensate for and drawn The capacitance difference between Y touch electrode wire (Y-TEL) risen.

That is, in the single-layer touch sensor structure according to the display panel (DISP) of embodiment of the present disclosure In, can by adjusting the area of Y touch electrode (Y-TE) or X touch electrode (X-TE) come compensate due to Y touch electrode connect Capacitance difference between Y touch electrode wire (Y-TEL) caused by the length and arrangement of line (Y-CL), to improve touch Energy.

Additionally it is possible to compensate Y by adjusting the area of both Y touch electrode (Y-TE) and X touch electrode (X-TE) Capacitance difference between touch electrode wire (Y-TEL).

Although Figure 21 and Figure 22 instantiate Y touch electrode connecting line (Y-CL) showing around X touch electrode wire (X-TEL) Example, but the structure of above-mentioned touch electrode (TE) can be applied to wherein X touch electrode connecting line (X-CL) and bypass Y touch electricity The structure of polar curve (Y-TEL).

Figure 23 to Figure 26 instantiates the single-layer touch sensor of the display panel (DISP) according to embodiment of the present disclosure The detailed example of the structure of touch electrode (TE) in structure.

Figure 23 is in the single-layer touch sensor structure illustrated according to the display panel (DISP) of embodiment of the present disclosure Touch electrode (TE) structure the first exemplary view, wherein the area of touch electrode (TE) is not adjusted.

Referring to Figure 23, in the display panel (DISP) according to embodiment of the present disclosure, a plurality of X touch electrode wire (X- TEL) and a plurality of Y touch electrode wire (Y-TEL) can be arranged to it is intersected with each other within the same layer.

Each in a plurality of X touch electrode wire (X-TEL) includes that multiple X touch electrodes (X-TE) and a plurality of X touch electricity Pole connecting line (X-CL), and multiple X touch electrodes (X-TE) pass through the X touch electrode connecting line (X- being arranged between them CL it) is electrically connected to each other.That is, X touch electrode (X-TE) included in X touch electrode wire (X-TEL) can be along first Direction (for example, X-direction or x-ray) is connected to each other.

Each in a plurality of Y touch electrode wire (Y-TEL) includes that multiple Y touch electrodes (Y-TE) and a plurality of Y touch electricity Pole connecting line (Y-CL).In addition, multiple Y touch electrodes (Y-TE) surround X touch electrode wire (X-TEL) at least by being arranged to The Y touch electrode connecting line (Y-CL) of a part is electrically connected to each other.That is, included by Y touch electrode wire (Y-TEL) Y touch electrode (Y-TE) can be connected to each other along the second direction (for example, Y direction or Y line) intersected with first direction.

Therefore, Y touch electrode connecting line (Y-CL) can be disposed in X touch electrode (X-TE) and Y touch electrode (Y- TE in the region between).In addition, since X touch electrode wire (X-TEL) is by included in each Y touch electrode wire (Y-TEL) The part that surrounds of Y touch electrode connecting line (Y-CL) it is different from each other, therefore can be touched in X touch electrode (X-TE) and Y electric There is the white space without arrangement Y touch electrode connecting line (Y-CL) between pole (Y-TE).White space can have Along X touch electrode (X-TE), Y touch electrode (Y-TE), X touch electrode connecting line (X-CL) and Y touch electrode connecting line (Y- At least one of) CL the additional pattern (AP) of arrangements.Additional pattern (AP) is described later with reference to Figure 28.

Although Figure 23 is shown in which that the X touch electrode wire (X-TEL) arranged along same x-ray is divided and is arranged in the Example in one region and second area, but can also be divided along the Y touch electrode wire (Y-TEL) that same Y line is arranged And it is arranged in by dividing in the first area and second area that display panel (DISP) is obtained.

In above-mentioned single-layer touch sensor structure, Y touch electrode connecting line (Y-CL) is arranged to surround X touch electricity At least part of polar curve (X-TEL), to be produced between Y touch electrode connecting line (Y-CL) and X touch electrode wire (X-TEL) Raw capacitor.In addition, since Y touch electrode connecting line (Y-CL) included in each Y touch electrode wire (Y-TEL) has difference Length and position, therefore difference may be present in the capacitor as caused by each Y touch electrode wire (Y-TEL).

It, can in order to minimize the capacitance difference due to caused by the length of Y touch electrode connecting line (Y-CL) and position With by Y touch electrode connecting line (Y-CL) be arranged so that X touch electrode wire (X-TEL) by Y touch electrode connecting line (Y- CL) part surrounded minimizes.

For example, about Y touch electrode (Y-TE) Y28 included in the 8th Y touch electrode wire (Y-TEL-8), the 8th Y touching Touch the left end that electrode connecting line (Y-CL-8) is connected to Y touch electrode (Y-TE) Y28.Therefore, it is possible to use being touched in by the 8th Y 8th Y touch electrode connecting line (Y-CL-8) of included Y touch electrode (Y-TE) electrical connection in electrode wires (Y-TEL-8) Length minimizes.

As described above, the length of the Y touch electrode connecting line (Y-CL) by making encirclement X touch electrode wire (X-TEL) is most Smallization can be such that the capacitor generated between Y touch electrode connecting line (Y-CL) and X touch electrode wire (X-TEL) minimizes, thus Reduce the capacitance difference between Y touch electrode wire (Y-TEL).

However, even if the length of Y touch electrode connecting line (Y-CL) is minimized, but due to Y touch electrode connecting line (Y-CL) it is arranged to surround X touch electrode wire (X-TEL) and included Y touching in each Y touch electrode wire (Y-TEL) Touch between electrode connecting line (Y-CL) that there are length differences, therefore can there are capacitance differences between Y touch electrode wire (Y-TEL).

Therefore, each Y touch electrode wire is being considered according to the single-layer touch sensor structure of embodiment of the present disclosure (Y-TEL) it is provided in the case where the length of included Y touch electrode connecting line (Y-CL) in for touching electricity by adjusting Y The area of the area of pole (Y-TE) or X touch electrode (X-TE) compensates the capacitance difference between Y touch electrode wire (Y-TEL) Structure.

Figure 24 is in the single-layer touch sensor structure shown according to the display panel (DISP) of embodiment of the present disclosure Touch electrode (TE) structure the second exemplary view, wherein the area of Y touch electrode (Y-TE) has been adjusted.

Referring to Figure 24, in the single-layer touch sensor structure according to embodiment of the present disclosure, a plurality of X touch electrode wire (X-TEL) and a plurality of Y touch electrode wire (Y-TEL) be arranged to it is intersected with each other within the same layer.

A plurality of X touch electrode wire (X-TEL) includes multiple X touch electrodes (X-TE) and a plurality of X touch electrode connecting line (X- CL), and multiple X touch electrodes (X-TE) pass through the X touch electrode connecting line (X-CL) being arranged between them and are electrically connected each other It connects.Include in X touch electrode wire (X-TEL) other than being arranged in the X touch electrode (X-TE) at outermost position All X touch electrodes (X-TE) can have identical area.

M included X touch electrode wire (X-TEL), which can be, in above-mentioned single-layer touch sensor structure is applied touch The driving touch electrode wire of driving signal, and its n Y touch electrode wire (Y-TEL) can be detection touch-sensing signal Sense touch electrode wire.

On the other hand, n Y touch electrode wire (Y-TEL) can be the driving touch electrode for being applied and touching driving signal Line, and m X touch electrode wire (X-TEL) can be the sensing touch electrode wire of detection touch-sensing signal.

It therefore, can be by driving one of m X touch electrode wire (X-TEL) and n Y touch electrode wire (Y-TEL) And the touch based on mutual capacitance is sensed by sensing another kind.

It is applied to the touch driving of one of m X touch electrode wire (X-TEL) and n Y touch electrode wire (Y-TEL) Signal can be the signal with constant voltage level, or can be the signal with variable voltage level.

If touching driving signal has variable voltage level, touching driving signal can have such as square wave, sine The various waveforms of wave, triangular wave (copped wave) etc..

The frequency of touch driving signal can be constant or variable.

If the frequency for touching driving signal be it is variable, be supplied to touched with the corresponding X of driving touch electrode wire it is electric The frequency of the touch driving signal of polar curve or Y touch electrode wire can change randomly or according to pre-defined rule.

If changed with touching the frequency accidental of driving signal, frequency can be in scheduled frequency range (for example, 200kHz Or it is higher) in change.

As described above, can consider to include corresponding if the frequency for touching driving signal changes according to pre-defined rule Change frequency in the case where the time constant (for example, RC retardation ratio) for driving the signal transmission path of touch electrode wire.

According to the frequency shift technology for touching driving signal, can prevent due to the length difference between signal transmission path and Caused touch sensitivity deterioration, and can avoid executing while noise in touch display unit and touch driving.Under Description is changed the method for touching the frequency of driving signal by Wen Zhong in the case where considering time constant according to pre-defined rule. It touches driving signal (or touch-sensing signal) and transmits institute between touch-sensing circuit (TSC) and corresponding touch electrode (TE) By signal transmission path length can with the length and X of X touch electrode wire (X-TEL) touch wiring (X-TL) length Summation it is corresponding.

One X touch electrode wire (X-TEL) includes multiple X touch electrodes (X-TE) and touches for connecting the multiple X The a plurality of X touch electrode connecting line (X-CL) of electrode (X-TE).Therefore, the length of an X touch electrode wire (X-TEL) can be right Ying Yu is by by the multiple X touch electrode (X-TE) and a plurality of X for connecting the multiple X touch electrode (X-TE) Whole length of touch electrode connecting line (X-CL) are added and the value of acquisition.

The length of signal transmission path corresponding with m X touch electrode wire (X-TEL) can according to their position and that This is different.Therefore, it is normal to can have the time different from each other for signal transmission path corresponding with m X touch electrode wire (X-TEL) Number.Time constant can be such as RC retardation ratio (Resistance-Capacitance delay).The difference meeting of time constant between signal transmission path Lead to the difference of the touch sensitivity between signal transmission path, to reduce touch-sensing performance.

Similarly, due to the difference of the length between signal transmission path corresponding with n Y touch electrode wire (Y-TEL), It will lead to touch-sensing reduced performance.

Therefore, the length depending on the signal transmission path for touching driving signal is applied to m X touch electrode wire (X-TEL) frequency of the touch driving signal of the one or more items in can be different from each other.Alternatively, n Y is applied to touch The frequency of the touch driving signal of one or more items in electrode wires (Y-TEL) can be different from each other.

Therefore, by via frequency variation to due to touch sensitivity caused by the length difference between signal transmission path Variation compensates, and can improve touch-sensing performance.
